N27 error but cable is plugged in

Hi. I’m getting the n27 error saying that an Ethernet cable isn’t plugged in. Have never had to use an Ethernet cable until recently but Have bought a new cable and tried it in all the Ports on the hub. Still not working - can only get BBC1! I’ve had this issue since December but really would like to be able to access the TV now.
